Blood vessel

some of the differences in veins and arteries. The arteries in the systemic system, deliver oxygenated blood from the heart, in a high pressure low volume stream to the capillaries found throughout the body. The systemic veins carry the deoxygenated blood from the capillary beds in a low pressure, high volume, valve controlled flow, back to the heart. From there, the heart pumps the deoxygenated blood through pulmonary artery to be taken to the lungs to replenish the oxygen in the hemoglobin.…

system moves blood through the body and is made up of the heart, blood vessels and the blood. The lymphatic system moves lymph to various parts of the body and is formed by the lymph, lymph vessels and the lymph nodes. One of the largest functions of the circulatory system is to transport oxygen and remove carbon dioxide. All cells of the body need oxygen to stay alive. The circulatory system is a closed system that does not come in contact…

oxygenated blood from the lungs and pumps it to the cells and tissues to the body. The blood then returns to the right side of the body this is called systemic circuit. From the heart blood flows through large muscular arteries, then into smaller and smaller arteries, then arterioles and finally to the capillaries. It’s in the capillaries where the diffusion process takes place to exchange molecules of oxygen and nutrients for carbon dioxide of nearby cells, after leaving the capillaries blood…

heart is part of the circulatory system which pumps blood and supplies oxygen throughout our body(Jacobs). Pumped through a network of arteries and veins, blood is a very important part of our body. Without blood, we could not live. This is because it keeps us warm, fights off infections, and helps get rid of waste(Durani). Blood also transports oxygen and hormones throughout our body. Our circulatory system is made up of the heart and blood vessels. They also include arteries, veins, and…

is redness which is due to vasodilation- the widening of blood vessels and bleeding in the joint or structure). The clotting mechanism is the process of blood changing from its usual liquid state to a solid form. The clotting happens straight away after a blood vessel gets injured. There are three stages of the clotting mechanism, the first part is about the formation of prothrombinase. The formation of prothrombinase is when liquid blood gets into contact with some molecules.…

entire human body. Veins, arteries, capillaries, all carry blood that is being pumped by the heart throughout the body. Oxygenated blood from the lungs travels to the arteries and around the body, and then this blood is carried back through veins to be reoxygenated. Hemoglobin, a vital protein present in blood, binds to oxygen as you breathe air in. The oxygen in the air enters the alveoli and is picked up by the hemoglobin in the blood as it flows through the alveoli’s capillaries, and the…

The arteries are blood vessels that deliver oxygen and nutrients to all organs in the body during the heart pulses. During the blood circulation a pressure is exerted on the walls of the blood vessels or arteries. The case where the ability of such walls to expand or contract in response to blood pressure changes is called Arterial Stiffness (AS). Arteries need to be flexible to expand when oxygen is needed by muscles and heart, and stiffening of the arteries place an extra load on heart which…

characterized by blockage in the arteries at the base of the brain. As the normal blood vessels narrow and become blocked, a person may suffer from an ischemic stroke, hemorrhagic stroke, or a mini-stroke. Children and adults suffer from similar symptoms. During an ischemic stroke, a blockage interrupts the oxygen flow to the brain. A hemorrhagic stroke occurs in adults with Moyamoya when their blood vessel erupts and blood leaks into the brain.When a patient with the disease has one of the…

Modern day society is constantly moving and eliciting high profiles and demands while carrying with it both physical and psychological effects. These effects are commonly known as stress. Every person in this world has been under some sort of stress, whether it be big or small. How we react to the strain on both our minds and bodies can determine how well we cope under this prolonged stress, or better known as chronic stress. When presented under tension our bodies react by operating…

Superior Vena Cava Syndrome The Superior Vena Cava (SVC) is the main blood vessel that transports de-oxygenated blood from the upper body to the heart. The SVC is a short vein located in the anterior right Superior Mediastinum, which is the area found in the mid-line of the Thorax (Drake et al. 2010). The vein is surrounded by many structures involved in the respiratory and circulatory system including the right Bronchus and the Mediastinal lymph nodes (Martini & Ivonne 2004). Figure 1 is a…
